                                      Notes


1.   Accounting policies
     The accounting policies applied to the information in the earnings release
     follow International Financial Reporting Standards in effect as of the date
     of this release and are consistent with those applied in the 2005 Annual
     Report. Refer to the 2005 Annual Report, available at www.amvescap.com, for
     a more detailed discussion of these policies.

2.   Taxation
     A significant proportion of the tax charge arose from U.S., U.K., and
     Canadian operations. The effective tax rate is 36.9% for the first quarter
     of 2006 (first quarter of 2005: 35.7%).

3.   Earnings per share
     Basic earnings per share is based on the weighted average number of
     ordinary and exchangeable shares outstanding during the respective periods,
     excluding shares purchased and held by employee share ownership trusts.
     Diluted earnings per share takes into account the effect of the potential
     issuance of ordinary shares.
